Math, microeconomics or criminal justice
in rectangular coordinates (x,y) r^2 = x^2 +y^2
x = rcosT, y =rsinT
(6,-2) means x=6, y=-2
r^2 = 36+4 = 40
r =sqr40 = 2sqr10
h = hypotenuse = r
tan^-1(-1/3)= -18.435 degrees = 341.565 degrees
polar equivalent of (6,-2) = (r, T) = (magnitude, angle)
=(2sqr10, 341.565)
= about (6.325, 341.565)
